2 Claims. (Cl. 16-173) The present invention relates to new and useful improvements in hinge devices for vertically swingable screens, storm sash, cabinet doors, Windows or the like and more particularly to a concealed hinge structure.

An important object of the invention is to provide a concealed hinge structure for pivotally mounting a vertically swingable screen or the like in a window frame and embodying a novel construction for installing and removing the screen.

Another object is to provide a device of this character of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purpose for which the same is intended.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a view in elevation of a vertically swingable screen with parts shown in vertical section;

Figure 2 is an enlarged fragmentary sectional view taken on a line 22 of Figure 1;

Figure 3 is a top plan view showing the hinge in position for installing or removing the screen;

Figure 4 is a vertical sectional view taken on a line 4-4 of Figure 1;

Figure 5 is an enlarged group perspective view of the hinge; and

Figure 6 is an enlarged fragmentary perspective view of the hinge and interlocking connection for the pivoted window frame supported plate and the fixed screen plate.

Referring now to the drawings in detail, wherein for the purpose of illustration, I have disclosed a preferred embodiment of my invention, the numeral 5 designates a screen frame having rabbetted upper side portions 6 in each of which an elongated plate 7 is secured in a vertical position by screws 8. The lower portion of the plate is formed with a vertical slot 9 adapted to slidably receive a pin 10 having a T-head 11 and which projects laterally at the outer surface adjacent the free lower end of an elongated plate 12. Plate 12 is provided with a laterally projecting pivot pin 13 at its upper inner surface and which is pivotally inserted in an opening 14 in the upper side portion of a window frame 15. The screen frame is formed with an elongated recess 16 behind the fixed plate 7 to accommodate the head 11 of pin 10 to avoid interference with the free sliding movement thereof.

An ovate recess 17 is also formed in the side edge of the screen frame behind the fixed plate 7 to loosely receive a complementary shaped locking clip 18 having parallel outwardly curved flanges 19 at its side edges between which both the fixed plate 7 and pivoted plate 12 are received. The clip 18 is formed with a central opening 20 for sliding on a pin 21 anchored in the screen frame and a head 22 is formed on the outer end of the pin in front of the clip to retain the latter on the pin. A cylindrical recess 23 leads inwardly from recess 17 to accommodate a coil spring 24 and a washer positioned behind the clip to tensionally hold the latter outwardly in recess 17, as shown in Figure 2.

In the operation of the device, the pivot plates 12 are supported at the upper side portions of the window frame 15, and after the fixed plates 7, locking clips 18 and springs 24 have been assembled at the side edges of the screen frame, the pivot plates 12 are swung outwardly into a horizontal position, whereupon the T-heads 11 carried by said plates will be positioned vertically to enter the slots 9 of fixed plates 7, when the screen is held perpendicularly, as shown by full lines in Figure 3. The screen is then turned about the axis of pin 10 to swing the plates 7 and 12 into parallel relation with each other and are retained in confronting relation with each other by the T-head 11 being turned crosswise of slots 9. The plates are locked in parallel relation to each other by the plate 12 riding over one of the flanges 19 to enter the locking clip 18 into the position shown in Figure 2.

During the installation of the screen on the pivot plates 12, the slots 9 permit sufficient clearance from the window frame for this purpose, as shown by dotted lines in Figure 4, and the screen is then swung downwardly and pushed upwardly to fit closely in the window frame.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A concealed hinge structure for a vertically swingable closure comprising an elongated plate fixed in a position extending longitudinally of one side edge portion of the closure, an elongated plate pivoted adjacent one end to one side edge portion of an opening of a supporting structure wherein the closure is swingable, a pin and slot connection securing the first and second plates to each other, and means locking the plates to each other in parallel confronting relation to each other, said means comprising a channeled plate positioned at an edge of the closure behind the fixed plate and having a pair of spaced apart parallel flanges between which the first and second plates are engaged.

2. A concealed hinge structure for a vertically swingable closure comprising an elongated plate fixed in a position extending longitudinally of one side edge portion of the closure, an elongated plate pivoted adjacent one end to one side edge portion of an opening of a supporting structure wherein the closure is swingable, a pin and slot connection securing the first and second plates to each other, and means locking the plates to each other in parallel confronting relation, said means comprising a channeled plate positioned in a recess at an edge of the closure behind the fixed plate and between the flanges of which both the first and second plates are engaged, and spring means behind the channeled plate urging the latter in locking engagement with said first and second plates.
